BUNSEN GAS-BURNER.

SPECIFICATION :forming` part f Letters Patent N0. 425,246, dated April8, 1890. Application died June 20, 1889.. Serial No. 315,018. (Nomodel.)

To all whom it may concern:

Be it known that I, LEONARD PAGET, a citizen of the United States,residing at New York, in the county of New York and State of New York,have made a new and useful Invention in Gas-Burners, of which thefollowing specification, taken in connection with the accompanyingdrawings, constitutes a full, clear, and exact description.

My invention relates particularly to improvements in gas-burners of thattype Vknown as the Bunsen burner, or such as are designed to produceintense heat; and my object is to devise an improved form of this typeof burn er in which the shape or contour of the iiame may be regulatedto suit the requirements for which it is designed to use the burner. Iaccomplish this object by the apparatus hereinafter described, butparticularly pointed out'in the claims which follow this speeiiication.

Referring to the drawings, Figure l is a vertical sectional view of aBunsen burner with my improvement attached. Fig. 2 is a side elevationof the burner, showing the iinprovement; and Fig. 3 is a cross-sectionalview taken through the body of the burner.

A is the base, of Well-known forni,carrying the burner B, provided withusual air-inlet holes and a gas-distributer b, said burner beingconnected by a pipe t-o the supply of gas in the usual manner. Thedevice thus far described is of well-known construction.

C is a vertical rod, preferably screw-threaded at its lower end and heldin position by a nut, which is secured to the inner walls of the burnerB, as clearly shown in Figs. 1 and 3, the body of said nut havingsufficient bearing to hold the rod C in a central vertical position. Twoor more of such nuts located at some distance apart may be used, ifpreferred, in order to give vertical alignment and rigid support to theupright rod C.

e is a batiier or button, either rigidly attached to the rod C oradapted to a slide thereon, as preferred. If the lower end of the rod Cis not screw-threaded, as shown, butis held iixedly in position, thisbatlier or but-ton is then adapted to slide vertically upon said rod.

D is a funnel-shaped collar slitted at its lower end by slits d, so asto be adjustable scribed.

up and down upon the exterior surface of the burner B.

The arrows at the top of Fig. l of the drawings indicate the directionof the flow of the gas between the funnelshaped collar and the bafer orbutton e. By this arrangement of the adjustable collar and baftier thedirection of the iiame at the top of the burner is y changed asdesired,so that it may assume va- 6o rious contours. By adjusting therelative positions of these two parts I can, if desired, produce acylindrical iiame having considerable length and intense surface heat,thereby destroying the central core of the iiame now found to exist inan ordinary Bunsen burner, and which, therefore, for many applications,as in incandescent gas-lighting, is useless, the heating of such centralcore being wasted. The contour of the iiame may be so changed 7o by thiscombination of adjustable elements as to inii uence its position to suitthe varying requirements.

I do not limit myself to any special forni or shape of the adjustableparts herein shown and described, as I believe myself to be eutitled,broadly, to a burner of the type re ferred to, in which a baiiier orbutton e is adjustablevertically, or to a burner which is provided withan adjustable 'fianie-delieeting 8o collar, or toa combination of thetwo.

Having thus described my invention, what I claim, and desire to secureby Let-ters Patent of the United States, is

l. In a gas-burner of the Bunsen type, the combination of a baflier orbutton supported above t-he center of the burner with a vertically-adjustable deiecting-collar located at the top of the burner, substantiallyas de- 2. In' a gas-burner of the Bunsen type, the combination of avertically-adj ustable baffler or button with a vertically-adjustabledeflecting-collar located at the top of the burner, substantially asdescribed.

3. In a gas-burner of the Bunsen type, the combination of a rod securedadjustably to the interior of the burner and carrying a bafier or buttonat its upper end with an adjustable collar or defiector located at -thetop roc of the burner, substantially as described.

4. In a gas-burner of the Bunsen type, the

- combination of an adjustable baler or butcombination of a baiiier ordeiiecting-button adj ustably secured to the interior Walls of theburner with a funnel-shaped deecting-collar having a cylindricalbearing-surface about the upperend of the burner, which cylindrical ysurface is Slitted, whereby it is rendered adjustable, substantially asdescribed.
